The attempted repair of the UPS system did not fix the problem. It did, however, give us a high level of confidence that we can make further repairs to the system without shutting down the building systems. The field service personnel from the supplier will be in Monday morning to do the next level of repair, but we are not shutting down the building systems. If you have delicate research that would cause a major setback in your work, you may wish to defer processing Monday morning. While there is a very low probability of a problem, it is possible. Thank you for your understanding, John John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University (765) 494-5494 jrweaver@purdue.edu
